When someone sleeps with a person who is old enough to be their grandparent.

rocking the casket

When you sleep with someone who is old enough to be your grandparent. Much like rocking the cradle but reversed.

Hey have you seen Dylan? Yea he's upstairs rocking the casket with some granny he met at the bar.
